Trezor® Bridge Guide: Connect Your Device Smoothly and Safely
What Is Trezor Bridge and Why Do You Need It?
Trezor Bridge is the official, lightweight background software that allows your Trezor hardware wallet (Model One, Model T, Safe 3, Safe 5) to communicate securely with Trezor Suite (desktop & web) and hundreds of third-party cryptocurrency apps. It replaced the old Chrome extension in 2018 and is now the only officially supported way to connect your Trezor to modern browsers and the Trezor Suite desktop application.
Without Bridge running, your device will show “Connect your Trezor” errors even when physically plugged in.
System Requirements (December 2025)
Windows 10 version 1903 or newer (64-bit)
macOS 12 Monterey or later (Intel & Apple Silicon)
Ubuntu 20.04+, Fedora 34+, Debian 11+, or any recent Linux distro
One free USB port (USB-A or USB-C with included adapters)
Step-by-Step Installation
Go to the official page https://trezor.io/bridge
Click the big purple “Download Trezor Bridge” button. The site auto-detects your OS and serves the correct package (.exe, .dmg, .deb, .rpm, or AppImage).
Run the installer
Windows: Double-click the .exe → allow User Account Control → Finish
macOS: Open the .dmg → drag Trezor Bridge to /Applications → eject
Linux: Debian/Ubuntu: sudo dpkg -i trezor-bridge_*.deb Fedora: sudo rpm -i trezor-bridge_*.rpm AppImage: make executable and run
Bridge starts automatically and places a small “T” icon in your system tray (Windows/Linux) or menu bar (macOS). Green = running and ready | Gray = running but no device detected
First-Time Device Connection
Plug your Trezor into the computer using the original cable (or official Trezor USB-C cable for Safe 5/Safe 3).
If using Trezor Suite Web (suite.trezor.io), refresh the page.
If using Trezor Suite Desktop, it will detect the device instantly.
Unlock your Trezor with your PIN on the device screen (never on the computer).
Confirm “Allow connection” when prompted on the device touchscreen.
You’re now connected with full hardware protection.

Air-gapped signing: install Bridge on an offline computer, use “Export public key / Watch-only” in online Suite
Headless/remote use: trezorctl command-line tool is included with Bridge for scripting and server environments
